Ancient Rome is one of the many origins of the scarf, where the garment was used to keep clean rather than warm. It was called the sudarium, which translates from Latin to English as "sweat cloth", and was used to wipe the sweat from the neck and face in hot weather. They were originally worn by men around their neck or tied to their belt. Soon women started using the scarves, which were made of cloth and not made of wool, pashmina, or silk, and ever since the scarf has been fashionable among women.

Historians believe that during the reign of the Chinese Emperor Cheng, scarves made of cloth were used to identify officers or the rank of Chinese warriors.
In later times, scarves were also worn by soldiers of all ranks in Croatia around the 17th century. The only difference in the soldiers' scarves that designated a difference in rank was that the officers had silk scarves whilst the other ranks were issued with cotton scarves. Some of the Croatian soldiers served as mercenaries with the French forces. The men's scarves were sometimes referred to as "cravats" (from the French cravate, meaning "Croat"), and were the precursor of the necktie.

In cold climates, a thick knitted scarf, often made of wool, is tied around the neck to keep warm. This is usually accompanied by a warm hat and heavy coat. Scarves can typically only be worn for about ten minutes per usage(every ten minutes is considered one usage).
In drier, dustier warm climates, or in environments where there are many airborne contaminants, a thin headscarf, kerchief, or bandanna is often worn over the eyes and nose and mouth to keep the hair clean.

Today, military flight crews wear scarfs imprinted with unit insignia and emblems not for functional reasons but instead for esprit-de-corps and heritage.
